Gastric trichobezoar: an important cause of abdominal pain presenting to the pediatric emergency department.

Abdominal pain is a common presenting complaint of children seen in urgent care settings. It is the manifestation of a wide variety of disease processes ranging from benign to immediately life-threatening. Gastric bezoars are among the etiologies of chronic childhood abdominal pain that, when undiagnosed, may result acutely in serious complications, including gastric ulceration, bleeding and perforation, intussusception, and small bowel obstruction. To reinforce the importance of including this entity in the differential diagnosis of abdominal pain, we present the case of a 10-year-old girl with a history of chronic epigastric complaints who was ultimately presented with acute small bowel obstruction following fragmentation and distal migration of her gastric trichobezoar. Finally, we review and briefly summarize the current literature regarding the etiology, diagnosis, and management of this disorder in children.
